External Enwitech protection box for SolarEdge

Enwitech External Protective Enclosure for SolarEdge StorEdge SE5000-RWS

The Enwitech NL/BE external protection box is a complete technical solution approved by SolarEdge for securing photovoltaic installations with storage and backup functions. Specifically designed for the StorEdge SE5000-RWS single-phase hybrid inverter, this box intelligently manages the switchover between the public electricity grid and stand-alone back-up mode.

StorEdge system: autonomy and continuity of service

The SolarEdge StorEdge system combines photovoltaic production, battery storage and a back-up function to provide optimum energy autonomy. The Enwitech protection box is at the heart of the Backup function, enabling your installation to switch automatically to autonomous mode in the event of a power cut.

This solution is particularly suitable for installations requiring continuity of service to supply priority equipment:

• Residential homes: fridges, freezers, lighting, computers, internet boxes, etc.
• Offices and teleworking: IT equipment, servers, communication systems, etc.
• Sensitive installations: security systems, alarms, video surveillance, automatic gates
• Medical equipment: Devices requiring a continuous power supply for health reasons
• Home automation systems: heating, air conditioning, intelligent home management

Exclusive compatibility with SE5000-RWS

The Enwitech NL/BE cabinet is exclusively compatible with the SolarEdge StorEdge SE5000-RWS single-phase hybrid inverter. This limited compatibility ensures optimal integration and maximum system reliability, as all components have been tested and validated together by SolarEdge.

The external protective enclosure, the components used and the electrical cabling have been tested and approved by the SolarEdge manufacturer, guaranteeing the compliance and safety of your installation.

The SE5000-RWS inverter is a 5 kW hybrid inverter that simultaneously manages solar production, battery storage and consumer power, with the ability to automatically switch to Backup mode via this protection box.

Electrical characteristics and power

The electrical characteristics of the Enwitech box are suitable for single-phase residential installations with a back-up function:

The maximum power of 4.5 kW in Backup mode makes it easy to supply a home's priority equipment. The ability to temporarily ramp up to 7 kW for 5 minutes (300 seconds) means that equipment with high initial consumption, such as pumps or compressors, can be started up.

Management of earth connection diagrams

The Enwitech box provides compliant management of earthing systems in different configurations:

• Permitted diagrams in network mode: TT (neutral to earth) and TN-S (separate distributed neutral)
• Backup mode diagram: TN-S mandatory to guarantee electrical safety
• Mains disconnection: All poles (phase and neutral) disconnected during changeover.

This automatic management of neutral systems guarantees regulatory compliance and personal safety in all circumstances, whether the installation is connected to the public network or operating independently.

Robust construction and IP65 protection

The Enwitech enclosure is professionally built for durability and reliability:

• Polycarbonate enclosure: Robust, impact-resistant and UV-resistant material
• Colour similar to RAL 7046: modern, discreet grey
• IP65 protection rating: Dust-tight and protected against water jets
• Transparent lid: visual inspection without opening
• Tool-free closure: Easy access for maintenance
• Protection class II: Double insulation for enhanced safety

The compact dimensions of 448 x 432 x 161 mm (W x H x D) allow discreet wall mounting close to the StorEdge inverter and the general electrical panel. The 10 kg weight ensures stable and secure mounting.

Operating ranges and environment

The Enwitech enclosure is designed to operate in a wide range of environmental conditions typical of indoor installations:

These extended ranges guarantee reliable operation in the majority of installation environments, including unheated equipment rooms, garages or protected semi-outdoor spaces.

Compliance with standards and certifications

The Enwitech enclosure complies with the most stringent European standards for switchgear assemblies and energy storage systems:

• EN 61439-1: General rules for low-voltage switchgear and controlgear assemblies
• EN 61439-2: Power switchgear and controlgear assemblies (PTTA)
• EN 61439-3: Distribution boards for use by ordinary persons (ADB)
• VDE-AR-E 2510-2: Stationary electrical energy storage systems - Safety requirements
• RoHS compliance (2011/65/EU): Restriction of hazardous substances

These certifications attest to the quality, reliability and safety of the enclosure for use in residential and professional electrical installations.

Integration into your StorEdge installation

The Enwitech protection box is integrated between the public grid, the StorEdge SE5000-RWS inverter and the distribution board for priority consumers. Its role is threefold:

• Network monitoring: automatic detection of network outages or anomalies
• Automatic switching: Instant switching between network mode and backup mode
• Electrical protection: Proper separation of all poles and protection against short circuits.

The installation requires a specific configuration with separation of priority circuits (supplied in Backup mode) and non-priority circuits (cut off during network failures). This architecture optimises battery autonomy by backing up only essential equipment.
